Hello, Currently, the mesa bug mailing list is down, and Brian is on a vacation. So I'll just mail a bug report here. There is a bug in the CVS version of Mesa. It was there at apr26, and at may6 it's still in there. (Mesa-3.0 is OK) The bug manifests itself when doing drawelement calls from display lists. A glut program to demonstrate the bug is at: http://www.xs4all.nl/~stolk/hq/polarpyramid-matrix44-1.4.tar.gz it should compile out of the box. When started, press 'a' and 'l', which toggle arrays and lists. When both are active -> lighting disappears. The bug is recoverable: disabling either one makes the lighting come back. VERSION LISTS ARRAYS RESULT CVS Y Y BUG CVS N Y OK CVS Y N OK CVS N N OK 3.0 * * OK version tested: MesaCVS, may6, linux-i386-elf Mesa-3.0 does not have this bug.
